SEAT-SPRING.

memes.

Application `filed.Eeleruary To all whom it may concern Be it known thatI, VVILLmM C B-Inrriu, a citizen of the. United States, residing at'`Kalamazoo, Michigan7 have invented 1certain` new and useful'Improvements in Seat- Springs, ofwhich the followingivsa *specifi-f4cation.

seat springs. j y

My improved seat sprin'gis particularly similar seat boxes areemployedl.

provide` an improved detachable seat spring for seat boxes which maybequickly and"` easilyapplied or removedand one whichis` compact and.light in weight softhat it may be conveniently carried about and alsoone which is simple and economical in structure; Further 'objects7andobjects relating Ito structural details," will definitely appear fromthe detailed deseriptionto follow.;

` I accomplish theobjects of my invention bythe devices and meansdescribed in the" following specification. The invention is clearlydefined andy pointed out in the claims. c "A structure whichis apreferred embodiment of'myinvention `is clearly illustra'ted in the,accompanying drawing, forming a part ofthis specification, in which"Figure I is a detail vertical section of a structure embodying thefeatures of my in]` vention. Fig.` II is a perspective view of theAspringsupporting bracket with `the clarrip! in'g plate, springs and seatsupporting'rod removed. F ig. Ulis a perspective viewfof" the bracketclamping plate. f ln the drawing similar reference `characters refer tosimilar parts throughout the` several views. j i

Referring to the drawing, the structure illustrated is an engineers orlocomotive cab seat Lof' the seat box type in which 4a box 1 adapted asa tool or storage b'oX isp'r'ovided with a cover 2 hinged at 3 fandadapted as a seatE The cover is provided withl upholstery 4., Theseparts are shown in conventional form. Y f 7 .j provide a springsupporting bracket con-` sistingof a vertical armf5 adaptedto he`disposed against the inner side of the front wall 'pof the boX and anouter horizontal arm 6 resting upon the upperedge of the boX andprojecting beyond "the same.-1 `The SpeccatonrofLett-ers Patent.

inner horizontal arm 7 of the bracket is provided with a verticaldepending elongated :bearing S for the seat supporting bolt or rod 9;The clamping plate l0 is provided with atlange 1l at its'uppcr endadapted to rest on the top of the arm 6, the plate being r slotted at l2to receive the arm. rlhe flange This lnventionrelates to::improvements`1n lt is provided with an outwardly projecting portion `l?) having athreadedhole 14. therein n j for theset" screw 115. `This set screw isprodesigned by. me for. use` 1n any relation wheref1 vided with a wingedhead for convenience in adjusting. i The main obj ects of this inventionare to 1 `The coiled springslt and 17 are arranged onewithinlthe otherand their upper ends terminate in verticallyA disposed eyes 19which'engage the bolt 20 :arranged through the vertical arm ofthebracket so that the springs are supported toembrace the bearing S.'thebearing being spaced `from `the arm 5 to `accommodate the bolt 20.

The seat supporting rodl 9 is arranged through the horizontaleyes 2l atthe lower l ends ofthe springs. Nuts 22 are arranged above and below theeyes 21 to secure the rod to the springs so that the rod is yieldinglysupportedwithits upper end above `support the seat 2, as shown in thedrawing. Y

lVith' the parts thus arranged the spring may be quickly Iand easilyapplied to the seat box, the clamp being adjustable so as to accommodatevarying thicknesses of wall.

'Vith the parts thus arranged the stru@ .ture is compact and canbereadily carried aboutinthe pocket of the engineer so that he can takethe same from one engine to another or remove it when leavinghisengine.-

The structure is economicalto produce and at the sametimeis veryeffective for the purpose. i

Having thus described my invention, what Iclaim asnew andjde'sire tosecure by Letters'Patent,is:` 1`

l The combination with a boX provided with a cover hingedat 'one side,saidcover being adapted as a seat7 of a spring supportingbracket havinga vertical arm disposed against the inner side of the box and an outerhorizontal arm resting upon the upper edge thereof and projecting"beyond the same, and an "inner horizont-al arm provided with a vertical`elongated depending bearing spaced from- `said verticalfarm, anadjustableclamping plate having a flange at its upperT end `projectingat each side lli) CII
